+# <center>图像去噪</center>
+## 运行库
+cv2、matplotlib、numpy<br>
+contraharmonic_mean_filter.py、adaptive_median_filter.py
+## 高斯滤波
+利用高斯滤波处理高斯噪声。<br>
+运行gaussian.py程序进行高斯滤波处理。<br>
+如果需要修改处理文件，请修改gaussian.py文件中的照片路径。
+```c
+image_gaussian = cv2.imread("file/circuitboard-gaussian.tif")
+```
+程序效果展示如下。<br>

+## 反谐波均值滤波
+利用反谐波均值滤波处理胡椒噪声或盐噪声。<br>
+运行pepper_salt.py程序进行反谐波均值滤波处理。<br>
+如果需要修改处理文件，请修改pepper_salt.py文件中的照片路径。
+```c
+image_pepper = cv2.imread("file/circuitboard-pepper.tif", cv2.IMREAD_GRAYSCALE)
+image_salt = cv2.imread("file/circuitboard-salt.tif", cv2.IMREAD_GRAYSCALE)
+```
+程序效果展示如下。<br>

+## 自适应中值滤波
+利用自适应中值滤波处理胡椒噪声或盐噪声。<br>
+运行pepper_and_salt.py程序进行自适应中值滤波处理。<br>
+如果需要修改处理文件，请修改pepper_and_salt.py文件中的照片路径。
+```c
+image_saltandpep = cv2.imread("file/circuitboard-saltandpep.tif", cv2.IMREAD_GRAYSCALE)
+```
